IMPROVEMENT IN LOOM-SHUTTLES.

Specification forming part of Letters Patent No.152,419, dated June 23,1874; application filed July 7,1873.

To all whom it may concern:

Be it known that I, CALEB K. SAWYER, of Clinton, in the county ofVoreester and State of Massachusetts, have invented certain new anduseful Improvements in Shuttles; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon, which form a part of this specification.

My invention relates to shuttles used for wea-ving wire.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a plan view of my improved shuttle. Fig. 2 is a longitudinalsection, showing the method of unwinding the wire from the base of theconcavity out. Fig. 3 is a similar section, showing the method ofunwinding the Wire froln the base end and passing through the wholelength of the cop. Fig. 4 is a side View of the shuttle with the covertaken o", and Fig. 5 is a view of the inside of the cover.

A and B represent the caps or cups placed upon the ends of the wire cop.The conical end of the cop is placed in thecap A, the i11- ner side ofwhich is made smaller at the end than at the base. The other end of thewire cop is placed in the cap B, the inner side or" which is also madeslanting from the base to the end, but not as much as the cap A-onlyenough to get a suicient pressure upon the Wire. Both caps press againstthe wire so as to hold it perfectly upright, and this pressure isaccomplished by springs C C, of rubber or other suitable material, whichare attached to the caps and to the opposite ends of the shuttle, asshown in Fig. l. The caps A and B are used for unwindingV the wire fromthe base of the concavity out, and in the end of the cap B is a hole,through which the wire passes, rubbing against a pin, D; thence once ortwice around a grooved pulley, E, which effectually straightens it outfor weaving, after which the wire passes out of the shuttle. F Frepresent slats or tongues, attached to the sides of the caps,which,whenpassed into a groove in the cover and laid on a projection on theopposite side from the cover, keep the whole perfectly free fromrolling. Then the shuttle passes quickly into a shuttle-box and stopssuddenly, or as the wire weaves' out, the caps are pressed togethernearer as the Wire unwinds, and springs G, attached to the caps, catchin ratchets H,to hold the caps in the position to which they are drawn.I represents a hinged piece, which can be lifted to remove the cop andcaps, and is fastened down by a button, K. For unwinding the wire fromthe base end through the entire length of the cop, the base end of thecop is placed in a cap, L, which, with the exception of a conical-shapedpiece extending from the end to a little beyond the base of the cap, isthe same as cap B. The use of this piece is t0 keep the wire in anupright position; other- Wise it would be liable to tip over. Theconical end of the cop is placed in a cap, M, which is the same as thecap A, with the exception of a hole made in the end for the wire to passthrough. These two caps, L and M, are shown in Fig. 3.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. rlhe springs Gr and ratchets H, arranged with the caps A B, as andfor the purposes herein set forth.

2. In a shuttle for weaving wire-cloth, the combination of springs C C,caps A B, ratchet H, and spring Gr, all arranged as set forth Intestimony that I claim the foregoing as my own I atlix my signature inpresence of two witnesses.
